mostly straight, continuous, often attenuated above and subden- 

 tate, 20-25 x 4 /i, hyaline, conidia oblong or cylindrical, hyaline,

This was issued in N. A. F. but as far as we can find has not 

 heretofore been described.

Cercospora phyllitidis Hume 



On Polypodium Phyllitidis L., Hobe Sound, east coast of 

 Florida, March 14, 1900 (H. H. Hume). 



Spots brown, of irregular outline, 1-2 cm. diameter: fertile 

 hyphae, brown, sparingly septate, undulate, 60-80 x 3.5-4//, in 

 dense, spreading tufts thickly scattered over the spots on both 

 sides of the leaf but more abundant below, conidia lanceolate, 3-5- 

 septate, hyaline, 40-80 x 3-3.5 }*■ 



Cercospora smilacinae E. & E. 



On leaves of Smilacina scssilifolia Nutt, Latah Co., Idaho, 

 July, 1899 (Robert M. Horner, no. 1293). 



Spots amphigenous, oblong-elliptical, 2-4 X 1-2 mm., grayish- 

 white, bounded by a red line ; fertile hyphae mostly epiphyllous, 

 very short, 10-1 2x3 ft, crowded in dense tufts 35-50 ft diameter 

 which are soon obscured by a subcrustaceous, black mycelium oc- 

 cupying the center of the spots. The tufts of hyphae also appear 

 on dead areas of the leaf outside the spots, arranged in a seriate 

 manner between the nerves of the leaf: conidia filiform, subundu- 

 late or slightly curved, 40-60 x 2.5 ft, greenish or yellowish-hya- 

 line, with a single pseudoseptum near the middle, exceptionally 

 2-3 pseudoseptate. The fertile hyphae are hyaline with a brownish
